i To aZZ whom t-may concern l.Be litlknown that ywe,fJoHN J. GAYNOR and PETER CARL LIEBER, citizens ofthe United estates, and residents of Indianapolis, County jctv-Marion, andV State of Indiana, have invented a Icertain new andfuseful Bottle-Cap- ,ping vMachine; and wedo herebyv declare thatthefollowing is a full, clear, and exact description thereof, reference/being` had to the 1accon ipany'ing drawings, in which like letters refer to like parts.

.This invention relates =to compensating lmechanism in Abottle crowning or capping machines, the object ofsaid compensator being toallow bottlesof varying lengths to be successfullycrowned yor capped. The bottle'rest has auniform stroke in applying .the-cap tothe head. Heretofore-compensating devices in such machines .have had springs in them. On account of the varying action of springs from .time to time, for well-known reasons, the action of spring controlled compensators -is :not uniform., y

lhe yobj ect of #this linvention is 'to do away with .the springs -i-n icompensating 'devices xand 4make .such devices so that their Aactions will be uniform at all times, fondifl'ere'nt Y lengths .of bottles.

' Thechief feature of the invention 'consists in a pai-r of interlocking members with inclinedfengaging surfaces, 'one `of said lmembers being secured to 'the bottle support `and the other weighted, and an inclined brace ,plate for v'forcing the weighted member against rthe bottle supporting member, 'so 'that when the strain on the bottle support becomes too great. i-t will yield downward, forcing the Weighted member and brace plate sufficiently away to permit such action.

The full nature of the invention will be understood from the accompanying drawings and the following description and claims.l y y Y y In the drawings, Figure 1 is an elevation of a bottle capping machine with the parts' broken away and with the casing in central vertical section. Fig. 2 is a section on the Vline 2-2 of Fig. lV on an enlarged scale and with the parts broken away intermediate their ends and also broken away at the bot# tom and showing the parts inf normal position. ll`ig.l 3- is the same showing the parts atuatedposition; 4' is e; perspective :provement herein.

The) drawings herein illustrate' a type `of 'bottle capping machine whichisi'nowyin practical `use and which has a base 10 and casingll with a driving )shaft l2'and Adrivingpinion 13 meshing with a driving gear lisa table through whichtliebottlesupports reciprocate.

'l iAll of the foregoing mechanisml isold and Vconstitutes vno novel lpart of this invention excepting thef particular construction l of the bottle support iin connection The 'invention is `innsfarai in The bottle'supp'ort 15 :is Ya tube havingwith- `in it atransverse disk or 'plate'Ql 'ii'fwhich l Vthe 7bottle rests vand which is vv secured "to the tube 16`by ascrew 2Q. The bttle support? v4ing'tube Yl5 surround'sland'telescopes on the "14 for turning the bottle supports anfd which causes' the rotationof an annular seriesu of f tubular bottle supports 15;

'lov

upper 'end'of a compensator tube i23. Each l tube 23 @has a verticallopening 24in1one Si lthereof ,closed by 2a removable lplate '25,'. The Side wang ef the .tube 2s at therdpeng .2a are formed parallel with Veach "other, as 'shown in Fig. 5.

The baai@ Supporting rplate" 121 ige'- y .f

it has a weightrBQ l'onnthe lowerend ylifes against the friction plate 27'., and the ,adja r cent surface of'platel f orfi'iied4 with ife' cesses 33V adapted 'to receive; snugly. the lprop-p ibo jctions 29 and the lwerendof each re;

cess 33 there lis aninclined Y shoulder against which the inclined lower tend of .the

projection 29 bears'. l The outerside ofthe plate 31 hasin ita notch 35 intowhich a iiietr 3.6 en' .the upper' end, plate 37. extends loosely., .The

late Mii? of the' brace l placed in an inclined position with a projection 38 on its lower end entering a notch 39 in the wall of the tube 23, which is immediately above a block or plate 40 secured to the inner wall of said tube for the purpose of preventing the downward escape of the lower end of plate 37. The lateral shoulders 41 on the plate 37 bear against the friction plate 31 while the lateral shoulders 42 of plate 37 bear against the inner surface of the tube 23.

For lubricating the mechanism the tube 23 is closed by a disk 45 so that lubricating oil may be maintained in said tube and there are inclined oil conduits 46 through the bar 26 so that oil can pass and lubricate the adjacent surfaoe of the bar 26 and the tube 23.

The operation-is as follows: The angular position of the brace plate 37 bearing against the friction plate 31 will cause normally the plates 31 and 27 to remain interlocked, as shown in Fig. 2, and the weight 32 will coperate in this regard and also in maintaining the inclined position of brace plate 37. vWhile the bottle is being capped, it rests upon the disk 21 and if the downward strain thereon becomes excessive, the friction plate 27 will slip downward, as shown` in Fig. 3, by reason of the beveled surfaces or shoulders 30 and 34. Therefore, when bottles varying in size are being capped, this means for supporting the bottles will allow 'for said variations in size. The frictional engagement between the two plates 27 and 31, after the plate 27 starts downward, is still so great that it will prevent any sudden downward movement of the bottle support and, therefore, the contents of the bottle will not be agitated by the machine during the capping. When the friction plates are in the position shown in F ig. 3, considerable friction between them is still maintained because of the inclined position of the brace plate 37, causing friction between plates 31 and 27.

Since the tube 15 by reason of a shoulder 50 thereon is limited in its downward movement at the end of its capping process, as soon as a roller 5l passes down on a cam track 52, the weight of the tube 23 will move the friction plate 31 down into interlocking engagement with the friction plate 27 and place them in normal position with relation to each other and then thereafter when the cam rides up on the cam track 52, the tube 23 will elevate the tube 15 and all of the parts connected therewith as a union.

The construction is such that the mechanism is'accessible through plate 25. After removing the plate 25, the brace plate37 can be moved laterally out .of position and the friction plate 31 removed or replaced. There is practically no wear on the ends of the brace plate 37 because of the end thrust and if it were worn, it would be readily, re

placed. The brace plate 37 should be at 'an angle of less than forty-five degrees with relation to the wall of the tube 23 or more than forty-five degrees with relation to the friction plates 27 and 31. 1
